FDH-1 Fieldbus Diagnostic Handheld


FDH-1 is a portable fieldbus diagnostic handheld for physical layer testing. The device is designed for use in intrinsically safe fieldbus systems for FOUNDATION Fieldbus and PROFIBUS PA according to FISCO, Entity, and DART. The handheld examines segments during commissioning, maintenance, and troubleshooting.

The FieldConnex ® Fieldbus Diagnostic Handheld FDH‑1 is a comprehensive measurement and commissioning tool. The handheld can be connected to any point of a segment. Via display and push buttons, FDH‑1 guides the user through many scenarios of testing. FDH‑1 can record and store data for up to 32 segments with maximum device count without requiring a connection to a PC.

FDH‑1 supports inexperienced and expert users alike through different operating modes. Failure margin checks and device coupler tests help set up the optimum condition of the fieldbus infrastructure and find weak spots in the installation. The expert system and wizards enable easy handling and require little or no training. FDH‑1 supports multiple languages that can be downloaded onto the handheld.

FDH‑1 Manager Software Premium can operate the handheld with enhanced visualization. The software loads data from FDH‑1 and saves data back, to allow for comparisons between actual and planned physical layer attributes.

FDH-1 includes a keypad and a monochrome LCD with a resolution of 128 x 64 pixels. Easy interaction via keypad and LCD enable you to use the handheld independently of a stationary PC. FDH-1 can be segment-loop powered, battery-powered, or powered by a USB port. The supplementary handheld management PC software provides access to all measurement functions. For documentation purposes, you can upload and store data on the PC. The software supports multiple languages that you can download onto the handheld.
